چکیده

رابطه 40 لاین دابل هاپلوئید به همراه ژنوتیپ­ های والدینی و سه ژنوتیپ شاهد با عملکرد دانه و برخی از صفات مورفولوژیک جو با اجرای آزمایشی در قالب طرح بلوک­ های کامل تصادفی با دو تکرار تحت دو رژیم آبی (شرایط تنش و بدون تنش)، طی دو سال­ زراعی 92 و 1391 مورد بررسی قرار گرفت. نتایج تجزیه واریانس مرکب بیانگر اختلاف معنی­ داری بین سال، شرایط تنش، لاین­ ها و اثر متقابل لاین × سال برای اکثریت صفات اندازه­ گیری شده بود. مقایسه میانگین ­های گروهی بین شرایط تنش آبی و فاقد تنش نشان داد که لاین ­های دابل هاپلوئید از نظر تعداد دانه در سنبله، وزن هزار دانه، عملکرد بیولوژیک و عملکرد دانه، نسبت به ژنوتیپ ­های شاهد از درصد کاهش کمتری برخوردار بودند. ضرایب همبستگی بین صفات در شرایط تنش و فاقد تنش نشان داد که عملکرد دانه بیشترین همبستگی مثبت و معنی ­دار را با صفات عملکرد بیولوژیک، وزن هزار دانه، وزن هکتولیتر و شاخص برداشت داشت. بر اساس نتایج حاصل از رگرسیون گام به گام صفات طول پدانکل، تعداد دانه در سنبله، وزن هزار دانه و وزن هکتولیتر از جمله مهم­ ترین صفات مؤثر در افزایش عملکرد دانه بودند، به­طوری­ که درتجزیه علیت نیز صفات فوق در هر دو شرایط تنش و فاقد تنش اثر مستقیم بالایی بر عملکرد دانه داشتند. به ­طورکلی، با توجه به مقایسه میانگین ­های صفات و همچنین بر اساس شاخص ­های STI و GMP لاین­ های شماره 11، 13، 14، 18، 24، 29، 30، 35 و 39 به ­عنوان لاین­ های مطلوب از نظر عملکرد دانه و صفات مرتبط با آن و متحمل ­ترین لاین­ ها در پاسخ به تنش کم آبی شناسایی شدند.

چکیده [English]

To study the relationships of grain yield and some of agro-morphological traits in 40 doubled haploid (DH) lines along with parental and three check genotypes in a randomized complete block design with two replications under two water regimes (normal and stress) were evaluated during 2011-2012 and 2012-2013 growing seasons. Combined analysis of variance showed significant difference for all the traits in terms of the year, water regimes, lines, and and line × year. Comparison of group means, between non-stress and stress conditions, showed that DH lines had the lowest reduction percentage for the number of grains per spike, thousand grain weight, grain yield and biological yield as opposed to check genotypes. The correlation between grain yield with biological yield, harvest index, thousand grain weight, and hectoliter of kernel weight in both conditions, were highly significant and positive. Based on stepwise regression the peduncle length, number of seeds per spike, thousand seed weight, and hectoliter of kernel weight had important effect on increasing seed yield. The result of path analysis showed that these traits had the highest direct effect on grain yield. Based on mean comparisons of morphological characters as well as STI and GMP indices it can be concluded that lines No.11, 13, 14, 24, 29, 30, 35 and 39 were distinguished to be desirable lines for grain yield and their related traits and also tolerant lines in terms of response to drought stress conditions.
